A nervous newbie from 'Down Under' here. I've had Chronic Regional Pain syndrome in my right wrist/arm to shoulder for four and half years after work injury. Treated with all conservative methods. Nerve blocks - injections on regular ( 6 - 8 weeks) helped reduce pain to manageable levels for basic living but cannot work. Complication is I am Deaf and use Sign Language to communicate. Tricky with limited R wrist movement and being right handed. Really tricky when trying to communicate with technicians in theatre and partly sedated!! Have only been Deaf 10 years so can speak and lip-read when working with techs in office. Am currently having trial for this week. Am a tad (read BIG TAD) nervous about wires and things in my c-spine but desperate for pain relief. Realise I will possibly have a fight with insurance if this works but prepared for that and surgeon is supportive. Other problem is I am obese so what extra problem with implanting battery packs etc. Will I feel the pack when I am sleeping? I sleep on my sides (turn over often during the night). I also travel quite a bit. What are travel restriction re air travel? These are probably really silly questions sorry.
